Description

Drug-injecting smartwatch bandTechnical Field

[0001] The present invention relates to a smartwatch band having an automatic drug injection system during a cardiac arrest.Background Art

[0002] Cardiovascular diseases, including stroke and cardiac arrest, are significant contributors to human mortality, as highlighted by the World Health Organization. Despite advancements in medical science for prevention, the fatality rate associated with these conditions remains high. A major challenge leading to fatalities is the unpredictable nature of stroke or cardiac arrest occurrence. Though effective to a certain extent, current diagnostic tools and preventive measures often fail to provide timely intervention when an unexpected cardiac event occurs. Additionally, while inventors have made notable progress in diagnosing these conditions, a substantial portion of individuals at risk of such diseases are hesitant to adopt additional gadgets beyond their daily essentials. This reluctance is due in part to the inconvenience and additional effort required to use multiple devices daily.

[0003] In response to this need, researchers and inventors have conceived the idea of integrating specialized diagnostic features into smartwatches, devices that have become increasingly popular and are regularly worn by a large segment of the population. Smartwatches have evolved beyond simple timekeeping devices to sophisticated gadgets capable of tracking various physiological parameters, including heart rate, steps taken, and even sleep patterns. Despite these advancements, there remains a significant need for more integrated health solutions that can provide not only monitoring but also active intervention.

[0004] One innovative development in this field is the drug-injecting smartwatch, designed to seamlessly monitor and manage the user's health status. This device incorporates an integrated system that is both unobtrusive and convenient, ensuring continuous health monitoring while also providing a mechanism for drug delivery. The primary feature of this smartwatch is its ability to inject medication, which is particularly beneficial for patients requiring regular doses of specific drugs, such as insulin for diabetes management or epinephrine for severe allergicreactions. The injection mechanism in these smartwatches is typically positioned directly beneath the watch's panel, ensuring that it remains out of sight and does not interfere with the smartwatch's primary functions. The system is designed to be user-friendly, allowing the user or a caregiver to administer the injection as needed. This non-automatic approach ensures that the user retains control over the timing and administration of the medication.Summary of Invention

[0005] This summary is intended to provide an overview of the subject matter of the present disclosure, and is not intended to identify essential elements or key elements of the subject matter, nor is it intended to be used to determine the scope of the claimed implementations. The proper scope of the present disclosure may be ascertained from the claims set forth below in view of the detailed description and the drawings.

[0006] In a general aspect, the present disclosure relates to a drug-injecting smartwatch band designed to deliver medication through the skin of the wrist when worn. The band can include a smartwatch positioned on one side of the wrist and a security band for fastening around the user's wrist. The band may feature a controller unit configured to receive commands from the smartwatch and execute corresponding actions within the band. A perforated part can be provided on the security band near the injection unit to allow the injection members to penetrate the user's skin.

[0007] In one implementation, the injection unit may be attached to the security band on the opposite side of the smartwatch, positioned adjacent to the veins on the underside of the wrist. The injection unit may comprise a medication container configured to store medication for subsequent release to injection members, which can include microneedles arranged on an injection pad. The injection members can penetrate the skin to deliver the medication.

[0008] In one aspect, a thermoelectric cooling element can be coupled to the medication container to cool the medication, and activation means can be provided for activating the injection members. The band may synchronize with an application launched on the smartwatch to recognize an absence of pulse exceeding 30 seconds as a definitive cardiac event, prompting the thermoelectric coolingelement to compress the medication container, causing the injection members to pass through a perforated part and deliver medication into the veins of the wrist.

[0009] In another aspect of the present disclosure, the smartwatch band may also include integrated sensors on the smartwatch close to the wrist, a controller board to serve as an intermediary between the smartwatch and the security band, and a push button that activates the controller board when the security band is applied around the user's hand. The controller board can be provided with a rechargeable battery to power the smart band.

[0010] In a further aspect of the present disclosure, the thermoelectric cooling element may comprise a plurality of thermoelectric coolers with cold sides positioned in thermal contact with the medication container to facilitate cooling and hot sides positioned in thermal contact with the outer side of the security band to dissipate heat. The activation means may include an injection motor connected to the controller board and a cam attached to the axis of the injection motor to move in a circular motion beneath the thermoelectric cooling element. The controller unit and injection unit can be connected using one or more connection means, and the controller unit may further comprise one or more devices for visually indicating information coupled to the controller board. This design aims to enhance reliability, cost efficiency, and immediate response in emergencies, providing a robust and user-friendly solution for managing cardiac events and similar emergencies.Technical Problem

[0011] Current smartwatch models equipped with drug injection capabilities typically position the injection mechanism directly beneath the smartwatch's panel. This design necessitates the dependence of the injection system on the smartwatch itself, creating a critical limitation. The drug compartment within these devices must be regularly refilled, a process which requires the entire watch to be taken to a dedicated drug compartment changing station, potentially for an extended time. Any malfunction or issue during this period renders the injection system unusable, compromising the patient's safety and continuous treatment. Furthermore, these existing smartwatches lack full automation in their operation. When a patient suffers from a condition such as cardiac arrest, either the patient or someone nearby must manually activate the injection unit. This activation typically involves engaging a screw mechanism, which can be problematic if the patient isincapacitated or if no one is present to assist. Such scenarios can lead to dangerous delays in drug administration, significantly increasing the risk of adverse outcomes.

[0012] Current models of smartwatches that claim to offer automatic drug injection have the injection system situated behind the watch face. This placement brings several issues. As previously mentioned, it affects the overall usability of the smartwatch, often necessitating removal from the wrist for maintenance or refilling, which can be inconvenient and unreliable. Moreover, these smartwatches often utilize pneumatic systems to open and close the drug compartments. Pneumatic mechanisms, while innovative, introduce delays in the injection process. The reliance on such systems means that the drug is not administered instantly, which is critical during emergencies such as cardiac arrest where every second counts.

[0013] Another significant issue with current smartwatch models is the use of mechanical components for opening and closing the medication compartments. These mechanical systems often fail to seal the compartments adequately, leading to potential leakage. Leakage not only results in the wastage of precious medication but also raises serious safety concerns due to the risk of improper dosage administration and potential exposure to harmful substances.

[0014] A further drawback of current smartwatches with drug injection capabilities is the absence of an effective notification system. After the drug has been administered, there is no mechanism in place to alert nearby individuals or medical staff at a healthcare facility. This lack of communication can result in a critical delay in the follow-up medical treatment necessary after the initial drug administration, further endangering the patient's health.

[0015] In summary, while existing smartwatch models with drug injection systems offer a novel approach to emergency medical treatment, they suffer from several significant drawbacks. These include dependency on the smartwatch for drug compartment maintenance, lack of full automation requiring manual activation, delays in drug administration due to pneumatic systems, mechanical failures leading to leakage, and the absence of a notification system to inform others of the drug administration. Addressing these issues is crucial to enhance the reliability,effectiveness, and safety of smartwatch-based drug injection systems, particularly in life-threatening situations such as cardiac arrest.Solution to Problem

[0016] To address the aforementioned problems, this disclosure proposes the design of a modular smartwatch band with an integrated drug injection system that can be synchronized with any compatible smartwatch. This modular approach allows for the drug injection system and its controller unit to be housed within the band itself rather than the smartwatch. This design offers several significant advantages:

[0017] The band, which contains the drug injection system and controller unit, can be easily detached from the smartwatch. This feature allows for quick replacement or repair of the band without the need to replace the entire smartwatch. In the event of a malfunction or when the drug container needs to be refilled or replaced, the user can simply attach a new band. This ensures continuous functionality of the drug injection system without compromising the utility of the smartwatch.

[0018] By placing the injection system in the strap, the main smartwatch remains unaffected during maintenance or replacement of the drug container. This design reduces overall costs since only the band needs to be serviced or replaced, rather than the more expensive smartwatch.

[0019] The injection system in the band operates autonomously and is capable of detecting cardiac arrest. Upon detection, it automatically administers the required medication without the need for any manual intervention by the patient or bystanders. This automation is crucial for ensuring timely drug delivery, especially when the patient is incapacitated.

[0020] To mitigate the problem of drug leakage, the proposed design incorporates advanced sealing technologies: The drug compartments within the band are sealed using thin silicone membranes. These membranes are highly effective in preventing leaks and ensuring that the medication is securely contained until the moment of injection. The use of silicone, known for its durability and flexibility, enhances the reliability of the sealing mechanism.

[0021] The band is equipped with a notification system that activates immediately after the medication is administered. This system includes visual indicators, such as lights, to alert nearby individuals and medical staff. The notification ensures thatthose around the patient are aware that the drug has been injected and that subsequent medical procedures can be initiated promptly. This is particularly important for informing emergency responders and healthcare professionals upon the patient's arrival at a medical facility.The proposed smart band design effectively addresses the technical challenges identified in existing smartwatch-based drug injection systems. By integrating the injection system and controller unit into a detachable band, the solution enhances reliability, reduces costs, and ensures immediate drug administration during emergencies. The incorporation of silicone membranes prevents leakage, while the built-in notification system ensures timely awareness and subsequent medical intervention. This innovative design offers a robust and user-friendly solution for managing cardiac arrest and similar emergencies, providing patients and healthcare providers with greater confidence and improved outcomes.Advantageous Effects of Invention

[0022] The proposed modular smartwatch band with an integrated drug injection system provides several significant advantages over existing solutions. First, it allows for the injection system and controller unit to be housed within the band, enabling quick and easy replacement or repair without the need to replace the entire smartwatch. Second, this modular design enhances cost efficiency by isolating the maintenance and replacement requirements to the band, rather than the more expensive smartwatch. Third, the autonomous operation of the injection system ensures timely and reliable drug delivery, especially in critical situations such as cardiac arrest, without requiring manual intervention. Fourth, the use of advanced sealing technologies, such as silicone membranes, effectively prevents drug leakage, thereby enhancing safety and reliability. Lastly, the built-in notification system immediately alerts nearby individuals and medical staff postinjection, ensuring prompt follow-up medical treatment and improving overall patient outcomes.Brief Description of Drawings

The controller unit 300 can be also capable of learning from historical data to improve its accuracy and responsiveness over time. It may include a microprocessor, memory for storing patient data and health records, and communication modules for syncing with external devices such as smartphones and healthcare provider systems. The controller unit 300 can also receive remote updates, ensuring that it remains up-to-date with the latest medical protocols and software enhancements.

[0033] In addition to its autonomous capabilities, the smart band 100 provides various user-interactive features. It can alert the user through visual, auditory, or haptic feedback in the event of a detected health issue. Users can manually trigger the injection unit 200 if they are aware of an impending health crisis. The smart band 100 also supports logging and sharing health data with medical professionals for further analysis and personalized medical advice. This comprehensive approach ensures that the smart band 100 not only acts as an emergency response tool but also as a continuous health companion, providing valuable insights into the user's well-being and supporting proactive health management.

[0034] Referring to FIG. 1 , in an exemplary embodiment, the controller unit 300 of the smart band 100 may comprise a security band 120 fastened around the user's arm, coupled with a smartwatch 110. The security band 120 ensures that the smart band 100 remains in place and maintains consistent contact with the user's skin for accurate sensor readings and effective medication delivery. The smartwatch 110, which is physically integrated with the security band 120, includes a body containing the smartwatch's logic and various sensors. These sensors are capable of measuring a range of biometrics such as heart rate, blood oxygen levels, motion, location, and user activity. The smart band 100, which contains the injection unit 200 and controller unit 300, can be easily detached from the smartwatch. This feature allows for quick replacement or repair of the security band 120 without the need to replace the entire smartwatch 110. In the event of a malfunction or when the medication container 218 needs to be refilled or replaced, the user can simply attach a security band 120. This ensures continuous functionality of the drug injection system without compromising the utility of the smartwatch.

[0035] According to one exemplary embodiment illustrated in FIG. 1 , the security band 120 may designed to comfortably attach the smartwatch 110 to the user's wrist, ensuring the sensors maintain close contact with the skin for accurate data collection.

This interface provides additional context and information that complements the LED and haptic alerts. For example, the dashboard can show the exact percentage of battery remaining, the time and dosage of the last medication injection, and the strength of the Bluetooth signal. This comprehensive approach to status monitoring ensures that users have all the necessary information to manage their devices effectively.

[0039] Further details on the configuration and operation of the controller unit 300 and the specifics of the injection unit 200 will be discussed in the description of FIGs. 2 and 3. These figures illustrate the internal architecture and functional mechanisms that enable the smart band 100 to perform its intended tasks.

[0040] According to some exemplary embodiment of the present disclosure, as illustrated in FIG. 2, the controller unit 300 of the smart band 100 may be provided with a controller board 310 comprising one or more of a processor, communication circuitry, and memory. Components of the controller board 310 can be configured to transmit, store, and / or analyze data, as described in further detail herein. The controller board 310 can be placed in the security band 120 and serve as the intermediary between the smartwatch 110 and the security band 120, receiving commands from the smartwatch 110 and executing the corresponding actions within the smart band 100.

[0041] Facilitating wireless communication, in some exemplary embodiment, the security band 120 may receive data from the smartwatch 110 through various wireless signals such as Wi-Fi, Bluetooth, cellular, and Zigbee, among others. For instance, the smartwatch's heart rate sensor may continuously monitor the user's heart rate while worn, triggering a command transmission via Bluetooth to theembedded controller board 310 in the security band 120 if a 30-second heart rate pause is detected.

[0042] Due to the necessity for the smart band 100 to inject the drug automatically, an activator for both the controller unit 300 and the injection unit 200 is required.

When the smart band 100 is secured around the wrist, this push button 314 can be activated, ensuring the device is properly positioned. Conversely, when the smart band 100 is removed or not correctly worn, the push button 314 is deactivated. This design minimizes the chance of accidental activation and guarantees that the controller unit 300 and the injection unit 200 are only activated when the device is properly in place on the user’s wrist.

[0044] Additionally, this activation mechanism can be complemented by an electronic verification system within the controller unit 300 as described in further detail herein. In some exemplary embodiment, the push button 314 can be connected to the controller board 310 to activate it. As shown in FIG. 2, when the security band 120 is applied around the user's wrist, the push button 314 may be pushed inward, activating the controller board 310. When the controller board 310 is activated, the Bluetooth circuit built on the controller board 310 can be also activated. With permission granted by the smartwatch 110, the pairing operation of the smartwatch 110 and the controller board 310 can be completed seamlessly, enabling the Bluetooth LED light 324 to be turned on.

[0045] In one exemplary embodiment, the required energy for the smart band 100 can be provided by a rechargeable battery 312, which is coupled to the controller board 310. In some exemplary embodiment, the rechargeable battery 312 can be a super-capacitor or a rechargeable lithium battery. These power sources are chosen for their high energy density, long life cycle, and ability to be quickly recharged, ensuring that the smart band 100 remains operational for extended periods.

[0046] In some embodiments, to monitor the status of the smart band 100 from the time it is closed on the hand to the final injection of medication, which includes several different stages, the controller board 310 can send different notifications at each stage. These stages may include the pairing of the controller board 310 with the smartwatch 110, the medication injection status, and the rechargeable battery 312 status. These notifications are communicated to the user via indicators.

[0047] In one embodiment, the controller unit 300 may further comprise one or more devices for visually indicating information, such as LED lights, LED screens, and the like. In a preferred embodiment, the notification LED lights may include the Bluetooth LED light 324, the Battery LED light 320, and the injection LED light 322 as mentioned before. As shown in FIG. 2, the LED lights can be arranged on the security band 120 coupled to the controller board 310. In this embodiment, the Bluetooth LED light 324 indicates the complete pairing of the controller board 310 with the smartwatch 110. The Battery LED light 320 indicates the rechargeable battery 312 status, and the injection LED light 322 indicates the completion of medication injection into the user's skin. Battery status may be visually indicated on smart band 100 with color-coded battery LED light displays 320 ranging from green (40-100% charge) to orange (20-40%), red (5-20%), and flashing red (below 5%), thereby enhancing the user's awareness of power levels.

[0048] In an exemplary embodiment, as shown in FIGs. 2 and 3, the controller unit 300 and injection unit 200 can be connected using one or more connection means317, such as the first connection means 316 and the second connection means318, as described in further detail herein.

[0049] In an exemplary embodiment, as shown in FIGs. 2 and 3, the controller unit 300 and injection unit 200 can be connected using one or more connection means317, such as the first connection means 316 and the second connection means318, as described in further detail herein. These connections ensure seamless communication and coordination between the various components of the smart band 100, enabling it to function efficiently and effectively in monitoring health metrics and administering medication.

[0050] The connection means 317 may comprise a set of conductive traces or a flexible ribbon cable embedded within the security band 120 that transmits electrical signals between the controller board 310 and the injection unit 200. This cable ensures that commands from the controller unit 300 are rapidly conveyed to the injection mechanism, enabling timely and precise medication delivery. The use of a flexible ribbon cable allows for durability and flexibility, accommodating the movements of the wrist without compromising the integrity of the connection.

[0051] In an exemplary embodiment, the injection unit 200 designed for medication administration through the skin, may be attached to the security band 120 on the opposite side of the smartwatch 110. In this embodiment, as shown in FIG. 2, the smartwatch 110 may be positioned on one side of the wrist, typically the dorsal side, while the injection unit 200 may be placed on the ventral side, adjacent to the veins. This placement ensures that the injection members 224 easily and quickly pass through the skin and inject the medication into veins. This strategic positioning leverages the anatomical advantages of the wrist, where the veins are more superficially located, facilitating efficient and less painful medication delivery. The thickness of the section where the injection unit 200 is housed within the security band 120 may be greater than the thickness of other areas of the security band 120. This increased thickness accommodates various components of the injection unit 200 and facilitates the movement of injection members 224 from within the security band 120 to the user’s skin.

[0052] The injection unit 200 must have an optimal mechanism that can be inserted into the security band 120 with an acceptable thickness and allow the injection members 224 to be inserted into the user's skin in a fully functional manner. The design of the injection unit 200 emphasizes minimalistic engineering to ensure that it integrates seamlessly into the security band 120 without adding significant bulk. The mechanism must be robust enough to reliably administer medication while being compact enough to maintain the aesthetic and ergonomic appeal of astandard smart band. To achieve this, the injection unit 200 can be placed in the security band 120 in such a way that the injection method is not interrupted by hand movements, ensuring that the injection operation is performed carefully and reliably. The integration ensures that the user's daily activities do not interfere with the functionality of the injection unit 200, providing a reliable and consistent administration of medication.

[0053] FIG. 3, clarifies in more detail what was disclosed generally in FIG. 2 and shows the injection unit 200 of the smartwatch band 100, consistent with one or more exemplary embodiments of the present disclosure. This figure provides a detailed view of the various components and their interconnections, illustrating how the injection unit 200 is incorporated into the security band 120.

[0054] In one embodiment, injection unit 200 may comprise a medication container 218 configured to store medication therein for subsequent release to injection members 224. As shown in FIG. 3, one or more injection members 224 can be provided to inject the medication through the skin on the injection side. The medication container 218 is designed to be quickly exchangeable and removable, allowing for easy refills and maintenance. Moreover, the shape of the medication container 218 may vary to suit different design requirements and user preferences. It can be round, oval, elliptical, crescent-shaped, half-sphere, half-oval, or another suitable shape. In this exemplary embodiment, the preferred shape and material of medication container 218 may be a silicon half-sphere container, chosen for its flexibility, durability, and biocompatibility.

[0055] In one embodiment, the medication container 218 may be coupled with a thermoelectric cooling element 220 for cooling the medication. This feature is particularly important for medications that require specific temperature ranges to maintain their efficacy. The thermoelectric cooling element 220 may comprise a plurality of thermoelectric coolers, each having a hot side and a cold side. The cold sides of the plurality of thermoelectric coolers may be positioned in thermal contact with the medication container 218 to facilitate cooling. The hot sides of the plurality of thermoelectric coolers may be positioned in thermal contact with the outer side of a security band 120, opposite the user's skin, to dissipate the heat removed from the medication container 218. This design ensures that the user's skin and themedication container 218 are not exposed to the heat generated by the cooling process.

[0056] As shown in FIG. 3, the medication container 218 of injection unit 200 may be partially surrounded by a flexible thin membrane 222, preventing medicine leakage when the smart band 100 is not worn or when injection unit 200 is not activated. In this exemplary embodiment, the flexible thin membrane 222 can be silicone. This material is chosen for its biocompatibility, flexibility, and impermeability, ensuring that the medication remains securely contained within the medication container 218 until it is needed.

[0057] In an exemplary embodiment, the injection members 224 delivering the medicine from medication container 218 to the user’s skin, may comprise an injection pad 210 attached to the medication container 218, and the plurality of microneedles 214. The injection pad 210 may be attached to the medication container 218 in the area where the flexible thin membrane 222 is located. As shown in FIG. 3, the medication container 218 and the injection pad 210 are separated by the flexible thin membrane 222, which is impermeable to the contents of both the container and the pad when the device is not worn or when injection unit 200 is not activated. This separation ensures that the medication is only released when the injection members 224 are activated, preventing accidental leakage.

[0058] In one embodiment, the plurality of microneedles 214 may be arranged on the injection pad 210, projecting at an angle from the injection pad 210. In a preferred embodiment, the plurality of microneedles 214 may be arranged in a plane perpendicular to the injection pad 210. Each microneedle 214 has a base portion 2142 connected to the injection pad 210, a tip-end portion 2144, and a body portion 2146 therebetween. The arrangement of the plurality of microneedles 214 is crucial for ensuring optimal skin penetration and efficient medication delivery. By positioning the plurality of microneedles 214 perpendicular to the injection pad, the device maximizes the surface area for injection and ensures uniform pressure distribution across the plurality of microneedles 214.

[0059] To minimize patient discomfort, the tip portion of the plurality of microneedles 214 may be sufficiently small and sharp to enable piercing and penetration of theskin with minimal pain. Each microneedle 214 may also include an elongated channel 2148 in the base portion and body portion of each microneedle, in fluid communication with the medication container 218 when the smart band 100 is worn. In this embodiment, channel 2148 may be open to two opposing surfaces of the plurality of microneedles 214. The elongated channel ensures a continuous and controlled flow of medication from the container to the target tissue. Usually, the plurality of microneedle 214 can be any elongated shape suitable for providing skin-piercing and fluid conduit functions, while minimizing patient discomfort. The use of the plurality of microneedles 214 significantly reduces the invasiveness of the injection process compared to traditional hypodermic needles, making it more suitable for frequent or chronic medication administration.

[0060] As mentioned before, the plurality of microneedles 214 needs to be inserted into the skin for drug delivery. The installation of the plurality of microneedles 214 on the inner part of the security band 120 that is placed directly on the skin causes skin scratches and sometimes leads to unwanted injection of medicine into the veins. To prevent these issues, the plurality of microneedles 214 can be positioned inside the security band 120 at a certain distance from the security band 120 surface. When injection unit 200 is activated, the plurality of microneedles 214 can be moved from the interior of the security band 120 to the skin and penetrate the veins for drug delivery.

[0061] For this purpose, an activation means 226 may be installed inside the security band 120 to move the plurality of microneedles 214, attached to the injection pad 210. Upon activation, the plurality of microneedles 214 can be moved from the inside of the security band 120 to the outside, making contact with the skin.

[0062] As previously mentioned, for the exit of the plurality of microneedles 214 from the security band 120, a plurality of holes can be provided in a specific area of the security band 120, referred to as perforated part 122. This area includes a plurality of holes that correspond to the number and thickness of the plurality of microneedles 214, enabling their precise alignment and controlled emergence from the band onto the skin. In one embodiment, as seen in FIG. 2, the perforated part 122 can be provided on the security band 120 near the injection unit 200 and adjacent to the skin, allowing the plurality of microneedles 214 to penetrate the user's skin through this part. The perforated part 122 can be designed to alignprecisely with the plurality of microneedles 214, ensuring that the plurality of microneedles 214 can extend and retract without obstruction. This design not only facilitates the injection process but also helps to protect the plurality of microneedles 214 when they are not in use. Additionally, perforated part 122 is designed with a certain number of holes to provide coverage for the injection unit, thereby preventing the entry of dust, sweat, and potential damage to the injection unit.

[0063] In one embodiment, the injection unit 200 may further comprise the activation means 226 for initiating the injection members 224. As depicted in FIG. 3, the activation means 226 may include a cam 216 and an injection motor 212, connected to the controller board 310 via the first connection means 316. In this exemplary embodiment, the cam 216 may be strategically positioned at a specified distance from thermoelectric cooling element 220. It may be designed to rotate upon activation by the injection motor 212, allowing one end to come into contact with thermoelectric cooling element 220. This rotational movement of the cam 216 effectively can move thermoelectric cooling element 220 toward the medication container 218.

[0064] As best shown in FIG. 3, the cam 216 may be attached to the axis of injection motor 212, enabling rotation of the injection motor 212 to move the cam 216 in a circular motion beneath the thermoelectric cooling element 220. This movement may cause thermoelectric cooling element 220 to move toward the medication container 218, thereby facilitating the pumping of medicine along the plurality of microneedles 214 by exerting pressure on medication container 218. The injection process may be meticulously controlled to minimize discomfort and ensure effective delivery of medication. The plurality of microneedles 214 are specifically engineered to fulfill both skin-piercing and fluid-delivery functions, requiring robust design to withstand insertion into and withdrawal from the skin.

[0065] In an exemplary embodiment, upon fastening the smart band 100 onto the user's wrist, the push button 314, which is connected to the controller board 310, can be pressed inward, thereby activating the controller unit 300. Activation of the controller board 310 initiates the built-in Bluetooth circuit, prompting a pairing process with the smartwatch 110 via a designated application. Upon successful pairing, the Bluetooth LED light 324 on the smart band 100 confirms a secureconnection by receiving commands from the controller board 310. Subsequently, the security band 120 synchronizes with the application launched by smartwatch 110. The sensors embedded under the smartwatch 110 continuously measure body conditions, such as heart rate. If there is a problem, for example, when the heart rate is absent for a certain period, the received information is analyzed by the application. Based on this analysis, the application program sends commands to the controller unit 300 to activate the injection unit 200.

[0066] For this purpose, the controller board 310 may order the activation of the injection motor 212. With the rotation of the axis of the injection motor 212, the cam 216 connected to the motor axis may rotate in a half-circle. The end part of the cam 216 can be placed under the thermoelectric cooling element 220, and upon contact, it moves the thermoelectric cooling element 220 towards the medication container 218. The movement of the thermoelectric cooling element 220 may cause the medication container 218 to move, resulting in the injection pad 210 located on the medication container 218 advancing towards perforated part 122. As the injection pad moves towards perforated part 122, the plurality of microneedles 214 embedded on the injection pad may exit perforated part 122 and penetrate the user's veins positioned in front of perforated part 122.

[0067] Simultaneously, the movement of the thermoelectric cooling element 220 towards the medication container 218 causes the medication container 218 to compress. The compression of the medication container 218 may force the medication out of the medication container 218, passing through the flexible thin membrane 222 and entering into the plurality of microneedles 214. Once the plurality of microneedles 214 enters the veins, the medication is released into the user's bloodstream.

[0068] In some embodiments, to accommodate the use of longer microneedles 214 and optimize the placement of the injection unit components while facilitating the injection operation, the thickness of the security band 120 in the region of the injection unit 200 may be increased. Concurrently, when the command is sent from the controller unit 300 to the injection unit 200, a command is also sent from the controller board 310 to activate the injection LED light 322. This light indicates the injection of one unit of medication, providing a visual alert to surroundingindividuals or medical staff that the medication has been administered, enabling them to proceed with post-injection operations.

[0069] One of the important parameters that should be considered in the correct injection of medicine in wearable gadgets is the correct placement of the elements used inside these devices. For example, in the current smart band 100, the controller unit 300 and the injection unit 200 must be correctly placed inside the security band 120 so that there is no issue with the precise and accurate injection of the medication. For this purpose, a plurality of grooves and protrusion may be embedded inside the security band 120 so that the elements used can be placed between these pluralities of grooves and protrusion, ensuring they remain in place during strong hand movements. However, concerning the injection unit 200, the plurality of microneedles 214, which must be ejected from perforated part 122 by the pressure exerted by rotating the cam 216, must move precisely in the desired direction to correctly exit perforated part 122 and penetrate the user's skin.To facilitate this, as shown in FIG. 4, an injection container 228 can be installed in line with the movement of the medicine container 218, the injection pad 210, and the plurality of microneedles 214 towards perforated part 122. The injection container 228 may have two open ends, with the medication container 218 placed in one end and the other end leading to perforated part 122. In this embodiment, the injection container 228 provides a specific path for the movement of the medication container 218 along with the injection pad 210 and the plurality of microneedles 214 towards perforated part 122. For this purpose, the inner wall of the injection container (228) may feature a plurality of elongated coupling grooves (230) extending from one open end to the other. Additionally, a plurality of coupling protrusions (232) may be provided on the periphery of the injection pad (210). These protrusions can be inserted into the coupling grooves (230), ensuring alignment and guiding the movement of the injection pad (210) within the injection container (228). The number of coupling protrusions (232) matches the number of coupling grooves (230), facilitating precise and aligned movement." i
